摘要：
Disclosed is a process for preparing a colorant of the formula wherein M is an atom or group of atoms capable of bonding to the central cavity of a phthalocyanine molecule, wherein axial ligands optionally can be attached to M, which comprises (a) reacting 3-n-pentadecylphenol with 4-nitrophthalonitrile in the presence of a base to form an alkylarylether adduct of phthalonitrile; and (b) reacting the alkylarylether adduct of phthalonitrile with either (i) a metal compound, or (ii) an ammonia-releasing compound in the presence of an alkanolamine solvent, or (iii) mixtures of (i) and (ii), to form the colorant.
